Fabrication of Three-Dimensional Photonic Crystals with Diamond Structure by SLA Technique

Abstract
It is difficult to fabricate three-dimensional(3D)photonic crystals.In this paper，the 3D photonic structure with diamond structure was fabricated by stereo lithography apparatus(SLA)as this technique can fabricate 3D structures no mat- ter how complicated they are.The lattice constant of the structure was optimized as 14.OOmm.The theoretic photonic bandgap Was ranged between 12.3GHz and 13.7GHz.Computer model of the crystal Was designed.The photonic crystal was prepared bv SLA.The transmission of microwave from 10 to 20GHz was measured indirection.A band gap is formed at the range of 12.3GHz to 13.4GHz.The magnitude of the maximum attenuation is as large as -26dB at 12.7GHz.which indicates that the fabricated structure works well as a photonic crystal.-
